The Sunex 7793B Telescoping Transmission Jack is a professional-grade heavy-duty solution engineered for the demanding work of transmission and transfer case removal, installation, and transport on lift-supported vehicles. With an impressive 1,000 lb. capacity and an extraordinary telescoping reach that extends from 35.5" to 79.5" in height, this jack gives technicians the vertical range needed to work comfortably with vehicles on lifts while maintaining precise control and stability throughout the entire service procedure.
Designed for serious professional shops and demanding fleet applications, the Sunex 7793B combines innovative telescoping ram technology with a robust 35" x 31.25" base that delivers exceptional stability under heavy loads. The foot-activated hydraulic pump pedal allows for hands-free raising, keeping your hands free to guide and position the transmission, while the foot-activated release pedal provides smooth, controlled lowering to protect both the equipment and the technician. Whether you're servicing light trucks, heavy-duty pickups, or commercial vehicles, this transmission jack gives you the reach, capacity, and control to get the job done safely and efficiently.
Telescoping Design for Maximum Versatility
What sets the Sunex 7793B apart from conventional transmission jacks is its unique telescoping ram system. The lowered telescopic rams enable easy transfer of transmissions from the jack to a work table or bench, then extend to reach a maximum working height of 79.5 inches—giving you the clearance needed to work with vehicles raised high on professional shop lifts. This extended reach eliminates the need for makeshift solutions or dangerous workarounds when servicing elevated vehicles, making transmission work safer and more efficient.
The telescoping design also means you can work at the optimal height for any vehicle configuration. Start low at 35.5" for initial positioning, then smoothly raise the load to the exact height needed for installation. The foot-activated pump pedal provides hands-free operation, allowing you to maintain control of the transmission with both hands while raising it into position—a critical safety feature when handling heavy, awkward loads.
Universal Saddle with Precision Positioning
The universal saddle features adjustable angle brackets that can be configured to match virtually any transmission pan shape or configuration. This adaptability means one jack can handle a wide range of vehicle makes and models, from domestic trucks to imports, without requiring special adapters or custom fixtures. The saddle tilts 53 degrees forward, 30 degrees backward, and 10-30 degrees side to side, providing the angular adjustment needed to align the transmission perfectly with the engine and bellhousing during installation.
A chain tie-down system secures the transmission firmly to the saddle, preventing shifting or tipping during transport and positioning. This added security is essential when maneuvering heavy transmissions through tight clearances or when adjusting the angle during installation. The combination of adjustable saddle brackets and secure tie-down ensures your load stays exactly where you need it throughout the entire service procedure.
Built-In Safety and Hydraulic Control
Safety is paramount when working with heavy transmissions overhead, and the Sunex 7793B incorporates multiple safety features to protect both technicians and equipment. The integrated overload valve prevents the jack from being used beyond its rated 1,000 lb. capacity, eliminating the risk of hydraulic failure or structural damage from overloading. This built-in protection ensures the jack operates safely within its design parameters at all times.
The foot-activated release pedal provides smooth, controlled lowering of the load, allowing you to carefully guide the transmission down while maintaining hands-free operation. Unlike twist-valve systems that can release suddenly, the foot pedal gives you precise control over descent speed, reducing the risk of sudden drops or loss of control. This controlled lowering is especially important when positioning transmissions onto work benches or when making final adjustments during installation.
